Hi Guys I've beeing looking for a flash data logger and to buy the best flash component to upgrade and analyze my RX8 actual performance, I've updated my coils some time ago so i think i should look at performance, besides i feed the car is getting too hot when i use it.

I feel like i need to know exactly and with real data the status of my car, and i will only get that with a data logger.

I searched and read something about mazda maniac and cobbAp but i'm not clear about it, all i ask is links at least to read..

I know some of you as usual are going to tell me there are threads, but this search sucks and you know it, thanks in advance...

MazdaEdit and the COBB AP are the two main options for flashing tools.

If you are mainly looking for status information though, just get an OBD2 reader that can read live data. I use a bluetooth OBD2 adapter paired with my tablet for information:


It's not a flashing tool, but it's far cheaper and you can use it across every car you own (1996+) and the flashing tools usually don't have good display options for seeing what all is going on live. The AP is restricted to only 1 data feed at a time, for example.

My car is a 2004, btw...

ahh you're right my bad, going to remove this thread...

Moved it to the right forum for you, and edited my response accordingly.

Hey thanks, i already bought a cheap obd2 reader, i don't really know how far this thing read, is a wireless one and i see it displays some data, but don't know if it's enough data i need to know if the car is ok.

it's a Mini ELM327 Wi-Fi OBD2 OBDII WiFi Car Diagnostic Interface Scanner For iPhone

An important part to hace a good performance is a good interpretation of the data logged, i have a cousin which is a EKU tech dealer and he knows about it, all i need is to find a way to get this data saved.

I'm looking something like this

RX8 Programmer

but i need to be sure it's what i need.

That device isn't logging itself, the application you are using does the logging. Not all apps can log, but there are apps that do that don't require you to buy more hardware. That device already presents all the data, you just have to have an app that can log it.

For example, if you had an Android device, I'd point you over to Torque, it can data log anything you want, and is $5 for the full version. I don't know what the iPhone options are, but I bet there is an app that will log for you.


And, just a tip:
We are pretty knowledgable on here too, and know more about this car than just about anyone else (Collectively). For example if you think your car is running hot, watch the OBD2 readout for coolant temp under various conditions. More accurate than your temp gauge on the cluster. Should stay under 220f.

Look at the Dynolicious or Rev apps for the iPhone.

Mmm cool didn't know torque does any data log, but my question is, how specific this logging stuff it is, I mean I've read about the Mazda Edit thing, it gives you all the hexadecimal data at points of the time with several environment conditions, that is very specific, there is another detail which it is called something like 'happy status' which tells you (in some old cars a value from 1 to 16, newer models a binary value 0/1) if the general status of your car is OK.

So, question: MazdaEdit is the software right, i need a cable right ? which is the additional hardware you're talking about.

You are overthinking things. Slow down a bit

The OBD2 port provides a method of 2-way communication with the ECU. ALL data that the ECU is designed to be able to report is available continuously through the OBD2 port. All OBD2 devices can see all data. However, the programming that is being the application side is what determines what to do with it, whether or not to display it, and what to log, if logging is even something that is designed. A basic code reader ignores everything except codes, for example.

The software can also transmit commands that the ECU will recognize, including code clearing at the most basic level, and complete replacements of the flash data at the high end.

HOW anything is displayed or logged is entirely up to the software, not the hardware.

Torque (using that as an example since that's what I know) has a HUGE list of OBD2 reported data points that you can log. It also has a list nearly as large of environmental data captured from the tablet or smartphone. Things like GPS data, acceleration / rotation sensors, signal strength, you name it.

It can also provide all of the system readiness monitors, which is what I assume you mean by "happy status".

MazdaEdit is basically Torque on steroids. Rather than using whatever OBD2 hardware you have on hand, it has it's own hardware, it has it's own software, it opens up everything specific to the RX-8's ECU rather than being a bit more generalized, and it can transmit flash data back to the ECU. The software also allows editing of data tables within an ECU flash file, which is where you get tuning capability.

If all you are looking for is system readiness monitors, you already have all the hardware you need, you just need to get the right app.
If all you are looking for is data logging, you already have all the hardware you need, you just need to get the right app.

The only reason you need MazdaEdit or a Cobb AP is if you want to change the flash file within the ECU, either to change the engine tune, block CEL codes from showing, or change other driving parameters, like the fan trigger temp point.

So, can you provide me a link where i can buy this MazdaEdit software/hardware ?

Ok I've just get my mini ELM327 to read my ECU, it is pretty cool actually, and there is a lot of data i can read from it, to my iphone, i've just did a quick test, i tried to reed my engine oil temperature but it didn't read it, i'll have to research more about it...

I've just made a 29 mile drive, than after an hour which is the time i test the elm327, i got that my Coolant temp is at 197 F.

So that's under 220 as you said, i suppose then is ok right ?

I thought my car is getting too hot cuz i think (not completely sure) i've been hearing the fan more than usual...

I've been researching to tun an acura integra 96 ECU thou, i think it is cheaper in case i messed with that ecu to buy a p06 for $20 instead of my rx8 ecu to be replaced

You will only get data for what the ECU is reporting. There is no oil temperature sensor (or oil pressure sensor) in the car, so the ECU can not report that. To get either of those, you have to add the hardware for it.

"driving for an hour" to check temp isn't the right way to think about it. It's all about the conditions and load you put on the engine. Like you want to watch for temperature spikes when sitting there idling, when getting on the gas hard, etc... Just driving around casually should have a very stable temperature even with an inefficient system.

Yes, 197F is just fine, if you can keep it there. Test for high load and idling temps though.

richcoto

i see, but as you told me low than 220F is ok, i thought driving for an amount of time would be a good test, as more the car is on as more the temperature would raise up, ok so, is it a guide i can follow to make a good test ?

Not so much the case if you understand how a car's cooling system works

RIWWP

iTrader: (2)

Yes, below 220 is good. What I'm saying is that you don't understand how engines produce heat and how the cooling system sheds that heat.

I recommend educating yourself on that first. I could spend a bunch of my time giving you tests and stuff, but if you don't understand how everything works together to keep the engine cool, and under what conditions the engine generates how much heat, it's not going to help you.

You are trying to run before you know how to walk.

richcoto

Sure you're right, going to read about it, then test according to the conditions i should test to see if the cooling system is ok.

As soon as i get that right now i just need to be sure car gets below 220F, thanks guys..

richcoto

Hey i think this could be interesting, if you can buy a cheap scanner like the obd2 elm327 you can get this software specifically for mazda i think and you don't have to guess what pid's you can use.
